All Clear Septic All Clear Septic and Wastewater Services are getting excited for the coming holiday. We know our customers are also looking forward to Thanksgiving and food preparation is well underway for thanksgiving meals. We would like to remind our customers to remember that it is very inadvisable to put any type of cooking oil, fat or grease down the sink to enter your septic system. If you regularly introduce cooking fats, oils and grease into your septic system it could result in a septic system failure. Just remember when you are making your beautifully juicy turkey dinne,r do not pour the fat, oil or grease down your sink. We have been conducting Septic Repairs in Hingham, Berlin, and Wayland, MA that could have been easily avoided with a little knowledge and preventative measures.  Call us at 508-763-4431 or visit for all your septic questions.
